GIBGULATORY SYSTEM F91! FURNACES Nb. segsee To all whom, it mag concernBe it known that I, BURT Lr-NooLN WORTHEN, a citizen oi: the U niterlStates,.and=

a resident of Tucson, in the county of'Pirna and Territory of Arizona,have invented a new and Improved Circulatory System for Furnaces, ofwhich the following is e full clear, and exact description.

My invention relates to furnaces, and more especially to furnaces of thevarious types used for metallur ical processes, such as reduction ofores. i

The more pericular object of m invention is to utilize the waste heat oft e water contained within the water jacket so as to im' rove thegeneraleificiency. of'tlie furnace, an .ulso to prevent the otherwiseob'cc'tiouable-efle'cts of the heat. Tot-his on 1, pro vide a.circulatory systemfor the water used, in the water jacket, the systembeingso; er-

- ranged that excessive heat of the furnace taken up by the water jacketand in turn transferred to the air or aiialogousjaeriform bodies usedfor supplying the oxygen and'the like to the furnace.

the bustle 14 upon that side, as indicated in Fig. 1; as the two sidesof the furnace are duplicates of each other only one s shown.

The coil 16 which constitutes a continuation of the pipe 37, and isinclosed within the bustle 14, hasa pipe 39, which is a continua-- tionof the coil 16 and leads to the source of supply for the water; anynumber of such ipes may be connected together if desired. The upperwater jacket is connected with the lower water jacket by U-tubes 41, andthese 'U-tubes are connected with twyer plates 42,

auxiliary drums 9 being in 0 en communication. with the water 8 in tjacket, tends to assume the ture as the water 8. The coils 12,therefore, tend to condense a portion of the steam formed within theauxiliary drums 9. In doing this the coils become heated and transeupper water same temperafer their heat to the medium flowing throughthem, to Wit, the water being pumped upward through the water pipe 29.This water, after passing through the various coils 12, descends throughthe pipe '33, and thus passes into the water jackets 23 and 6, and sincethese water jackets are in communication on each side by means of theU-tubes 41, it follows that the water passing upwardly through the pipe29 must the upper water jacket 6 and the auxiliary drums 9. Uponentering the lower water jacket 23 fronrthe pipes 33 and 34, however,the water, being mclosed, becomes warm, and therefore its introduction.into the jacket does nor produce any chilling effect there:

upon.

From all the drums 9 (see the upper leftand p01 tion of Fig. l) steampasses downwardly through the pipe 37' into the coil 16, which isinclosed within the bustle 14. The

heat radiated from the coil 1.6 raises the tem-' within the bustle 14,

perature of the medium this medium being air. The net result is that theair is heated, whereas the steam is cooled to such a degree thatcondensation ensues. The water of condensation thereupon passes throughthe pipe 39 to the-.source of supply, whence it is again pumped upthrough the pipe 29 and may be continuousl re-used.

As the water evaporating wit in the system above described "does notpass ofi as steam, but iscondensed and used over again, the waste ofwater is so slight as to become is revented by my system, bel

ultimately 'reac withinsaid with steam spaces,

the commercial success of operating furnaces.

By the use of my circulatory system a complete cycle of operations isperfected. The destructive heat of the furnace is taken up by water, andthis excessive heat thus taken up is utilized for the purpose of raisingthe temperature of the air or other aeriform body supplied to thefurnace, the steam bcing condenscd and returned in the shape of water tothe source of supply. Except for thee-old water passing through thecoils 12, the auxiliary drums 9 would be subjected to continuouslyincreasing steam pressure. If this pressure be relieved by means of avalve, not

only is there a waste of energy in the shape of heat units, but there isalso a Waste of water in the shape of steam passing off. This andthewater,

ore it reaches the lower jacket of the furnace, is rendered tolerablywarm, as above described.

Having thus described the preferred form of my invention, what I claimas new and desire to secure by Letters Patent is:
